Roberto Mancini has told his Galatasaray players that they should be confident of progressing past Chelsea and into the Champions League quarter-finals after overcoming what he described as an initial “fear” of Jose Mourinho’s team.

The former Manchester City manager had initially given Galatasaray only a “20 per cent” chance of beating Chelsea but, having equalised Fernando Torres’s ninth-minute goal last night, believes that their opportunity of winning the tie has now doubled.

“After this game, we have a 40 per cent chance to go through,” said Mancini. “We have more chance now than before the game. We played better in the second half and I’m confident after what I saw in the second half.

“We played with fear in the first 25 minutes and conceded a lot of space. They wanted this, this counter-attacking, because they’re strong on that. We made three or four mistakes, played with fear.

“When we started we had a lot of respect for Chelsea: we can’t have that respect for the opponents, ever. We should be more aggressive, like we did in the second half. We conceded what they wanted, on the

Mancini, though, believes that his players will ultimately have taken considerable self-belief from how the game ended and the way in which they dominated Chelsea during the second half.

“In London it will be a difficult game,” said Mancini. “But, after our second half, the players probably understand we can go through.”

Mourinho appeared unimpressed by Mancini’s attempt to place precise percentages on what might happen at Stamford Bridge, as well as his suggestion that Galatasaray had increased their chances of progressing.

“I’m not good at maths and football is not maths,” said Mourinho. “If football was maths, I’d coach in the third division. Because football is not maths, I coach Chelsea.”

Mourinho did note the intimidating atmosphere of the Turk Telekom Arena. “I just ask for 10 per cent of what this stadium gave Galatasaray when we play in three weeks,” he said. “It’s better to be 1-1 than 0-0, this result is better than the 0-0 we had in the first minute.”

Having dismissed Mancini’s attempt to take the credit for the Inter Milan team which won the Champions League in 2010, Mourinho also appeared to aim a subtle dig at the Italian over the Galatasaray team he inherited last summer.

“They were good last year, they are good this year,” said Mourinho. “Basically they’re a team that Fatih Terim built. Fatih did a great work and the team is really good.”
